AirPlans eSIM Data Plans for South Korea

AirPlans does not provide a true unlimited data eSIM for South Korea. All of its plans listed for South Korea have a specified data cap in the Data cap column, such as 3GB per day or 50GB total, and after the allocated amount the speed is reduced or the plan expires.

Instead, AirPlans offers a range of fixed‑data plans that can suit different needs. For example, the South Korea Unlimited 3‑day plan gives 3GB of high‑speed data per day for a total of 9GB, and the South Korea 50GB 15‑day plan offers a larger total allowance. Higher‑volume options are also available, such as the 100GB plans that are valid for 90 or 180 days. These fixed‑data plans are generally more cost‑effective than choosing a plan that claims “unlimited” but actually limits data or speed.

AirPlans does not offer any eSIM plans for South Korea that include a phone number or SMS capability. Currently only data‑only plans are available for this destination. Travelers who need to make voice or text calls can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these services are available in South Korea before purchasing a plan.

AirPlans lists 26 single‑country data plans and 41 multi‑country data plans available for South Korea. The catalogue includes both fixed‑data‑amount plans (34 in total) and daily‑data‑cap plans (33 in total). Prices range from about US $1.45 to US $382.07, while data caps span from 500 MB up to 100 GB and validity periods cover 1 to 180 days.
